Method and apparatus for reducing femoral fractures
First Claim
1. A method of reducing a femoral fracture, comprising:
- making an incision generally aligned with a patient'"'"'s greater trochanter;
developing a wound from said incision to the greater trochanter;
through said wound, creating a cavity in a femur, the step of creating the cavity including originating the cavity at the greater trochanter, extending the cavity from the greater trochanter into a femoral head, and extending the cavity from the greater trochanter into an intramedullary canal of the femur; and
positioning a femoral implant in said cavity.

Abstract
An improved method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure which does not require incision of the quadriceps. A femoral implant in accordance with the present invention achieves intramedullary fixation as well as fixation into the femoral head to allow for the compression needed for a femoral fracture to heal. To position the femoral implant of the present invention, an incision is made along the greater trochanter. Because the greater trochanter is not circumferentially covered with muscles, the incision can be made and the wound developed through the skin and fascia to expose the greater trochanter, without incising muscle, including, e.g., the quadriceps. After exposing the greater trochanter, novel instruments of the present invention are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur. After preparation of the femoral cavity, a femoral implant in accordance with the present invention is inserted into the aforementioned cavity in the femur. The femoral implant is thereafter secured in the femur, with portions of the implant extending into and being secured within the femoral head and portions of the implant extending into and being secured within the femoral shaft.
